(Re)moving buttons and address bar

I'm trying out Opera 25, and enjoying it for the most part, but there are a couple of things I miss from the older versions: Removing buttons that I do not use from the interface. That is, the back- and forward buttons, as well as refresh, which I have no use for, since I've always relied on mouse-gestures alone.

I've also always had the address bar at the bottom of my browser for many (10+?) years, but in this new version, I can't find a way to move it down.

Are there any plans to re-introduce these UI configuration options again? It would be very much appreciated!
